Systems and methods to use image data to perform authentication

Abstract

Image data from two different devices is used to identify a physical interaction between two users to authenticate a digital interaction between the users.

What is claimed is: 
     
         1 . A device, comprising:
 at least one processor configured with instructions for:   receive at least a first image and receive at least a second image from at least a first device;   based at least in part on the first and second images, identify a gesture performed between a first user and a second user;   perform authentication of the first and second users using the first device based at least in part on the identification of the gesture.   
     
     
         2 . The device of  claim 1 , wherein the instructions are executable by the at least one processor to:
 identify the gesture performed between the first user and the second user at least in part by identifying a gesture indicated in both the first image and the second image; and   perform the authentication based at least in part on identifying the first and second images as both being generated at a particular time that is indicated in time-related metadata.   
     
     
         3 . The device of  claim 1 , wherein the instructions are executable by the at least one processor to:
 identify the gesture performed between the first user and the second user at least in part by identifying a gesture indicated in both the first image and the second image; and   perform the authentication based at least in part on identifying the first and second images as both being generated within a threshold time of each other as indicated in time-related metadata.   
     
     
         4 . The device of  claim 1 , wherein the instructions are executable by the at least one processor to:
 perform authentication at least in part by identifying the first image and the second image as being generated at a same location.   
     
     
         5 . The device of  claim 1 , wherein the instructions are executable by the at least one processor to:
 perform authentication at least in part by identifying the first image and the second image as being generated by respective devices while within a distance of each other.   
     
     
         6 . The device of  claim 1 , wherein the instructions are executable by the at least one processor to:
 perform authentication at least in part by identifying the first image and the second images as showing a same physical interaction between the first and second users from different angles.   
     
     
         7 . The device of  claim 6 , wherein the physical interaction comprises a handshake between the first user and the second user. 
     
     
         8 . The device of  claim 6 , wherein the physical interaction comprises a high-five between the first user and the second user. 
     
     
         9 . The device of  claim 1 , wherein the authentication is in relation to exchange of a digital asset. 
     
     
         10 . The device of  claim 1 , wherein the device is a first device comprising a server, wherein the server is configured to communicate with a second device associated with the first user and from which the first image is received, and wherein the server is configured to communicate with a third device associated with the second user and from which the second image is received. 
     
     
         11 . The device of  claim 1 , wherein the device comprises a headset. 
     
     
         12 . A computer-implemented method, comprising:
 receiving a first set of images and a second set of images;   based on the first set of images, identifying a physical interaction between a first user and a second user;   based on the second set of images, identifying the interaction between the first user and the second user; and   based on identifying that the same physical interaction is represented in both the first set of images and the second set of images, authenticating an electronic interaction between the first user and the second user.   
     
     
         13 . The method of  claim 12 , wherein the interaction is identified based on identification of a gesture from both the first set of images and the second set of images and based on identification of the first and second sets of images being generated at least within a distance of each other within a time of each other. 
     
     
         14 . The method of  claim 12 , wherein the electronic interaction pertains to passing control of a digital asset. 
     
     
         15 . The method of  claim 14 , wherein the digital asset comprises a video game. 
     
     
         16 . The method of  claim 12 , comprising:
 identifying the electronic interaction at least in part by performing speech recognition using an audio stream of the first user and the second user speaking.   
     
     
         17 . An apparatus, comprising:
 at least one display;   at least one processor programmed with instructions to:   present on the display at least one user interface (UI) comprising:   a first option selectable to enable authentication via a physical interaction between at least first and second users.   
     
     
         18 . The apparatus of  claim 17 , wherein the UI comprises:
 a setting to select a particular predefined gesture as a gesture to be recognized to perform authentication.   
     
     
         19 . The apparatus of  claim 18 , wherein the particular predefined gesture comprises a hand contact gesture. 
     
     
         20 . The apparatus of  claim 17 , wherein the UI comprises an input element to enable a user to define the physical interaction.
